thanks, i purchased it, pretty good, tho it seems to lag a bit when switching, and for some reason does not accept all pictures, and is a little glitchy in the choosing of wallpapers, part of that was my fault, forgot which was portrait and landscape but in anycase still chose 2 diff wallpapers and it only used one and just gave a default was very strange, chose a different picture and it worked.

IN ANYCASE. i think its awesome great idea!

...if only someone could make something like this that allowed a different picture per page...

and also the lag you speak of is the actually setting of the wallpaper, takes less than 1 sec....
but this is a big improvement of when it took like 7 seconds in previous versions. (1.5 and 1.6 depreciated code)

also the app needs access to the sdcard, so if you mount your sdcard it won't find the picture...

future plans are to load the images into the app, not just the location.
and as for cropping... photoshop is far better than anything i can do on the phone
